MACHINE FOR UPSETTING CARRIAGE-TOP IRONS.

SPECIFICATION forming part of Letters Patent No. 373.614, dated November 22, 1867.

Application tiled January 12, 1886.

To (1% whom it may concern: I

Be it known that I, FRANK SCHREIDT, of Mansfield, county of Richland, and State of Ohio, have invented a new and useful Improvement in Machines for Upsetting Oarriage-Top Irons, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification.

My invention relates to the means for gaging the amount of stock oriron to be upset to form the knuckles and collars or other protuberances on carriage-top and similar irons, to the means for suspending the irons to be operated upon within the machine in proper relation to the clamping and upsetting dies, and to the means for actuating the movable portions of the clamping-dies, as hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a side elevation (partlybroken away) of a machine embracing my improvements. Fig. 2 is a plan View of the same. Fig. 3 represents a transverse vertical section on the line a: m, Fig. 2; Fig. 4, a partial plan view of the portion embracing the clamping and upsetting dies; Fig. 5, a perspective view of a portion of the clamping-bar; Fig. 6, a perspective View of the ends of the plunger-rods and of theiractuating-cams; Fig. 7, a perspective view of one of the suspending-hooks, and Fig. 8 detail views of the dies employed. Fig. 9 shows forms of the blanks after being acted upon by the dies.

The machine in its organization is similar to that described in another application filed by me of even date herewith, and it need,therefore, be described in detail only so far as is necessary to an understanding of the present improvements.

A represents the longitudinally-slotted portion or table of a frame of any suitable construction, in the rear end of which, in suitable bearings, is mounted the main driving-shaft B, provided with a band-wheel, B, through which it is operated from any convenient motor with a fly-wheel, B and at one end with a pinion, B engaging and actuating a spur-gear, 0, fast on a shaft, 0, located in hearings in Serial No. 188,360. (No model.)

the frame in front of shaft B, for imparting a continuous rotary movement to the latter in the direction indicated by the arrow 2.

The shaft 0 has a cam projection or rib, 0, formed upon it, which acts on a plunger rod or bar, D, connected with the plunger-block or cross-head D, for operating the movable part or parts of the die, as explained in my other application referred to, and upon the shaft 0, near the cam'c, is another cam-shaped projection or rib, 0, through which the movable clamping portions of the die are moved toward the fixed clamping portions for causing said portions to clamp or grasp and hold the iron to be operated upon by the dies, as will be explained.

The table portion A of the frame, as stated,

has a longitudinal slot formed in it at A, and

it is also recessed longitudinally in its upper face, forming fixed vertical ledges A and A, between which the parts of the die and the means for moving the movable parts thereof rest.

a and to indicate two parts of the die, which rest against the ledge A", and are held against lateral movement thereby.

a and a indicate the laterally-movable portions of the die. These rest against a longitudinal bar, A, adapted to move laterally in the recess in the table; and A is a longitudinally-movable bar or rod for actuating the bar A and moving it and the movable portions to and a of the clamp laterally for grasping the iron.

The bar A (see Fig. 5) has in its face adjacent to bar A a series of projecting frictionrollers, 12 b, and the bar A on the side adjacent to said rollers has a series of cam or wedge shaped projections, b'b,which, as the bar A is moved longitudinally forward, crowd the rollers b b and the bar A*, in which they are mounted, laterally, thereby moving the parts a and a of the clamping die laterally for clamping the iron to be operated upon against the parts a and a. The bar A has a longitudinal movement or forward thrust imparted to it for actuating the bar A and parts a and a of the die, as explained, by means of a pivoted rod or bar,D, projected within reach of and adapted to be operated upon by the cam projection c on the shaft 0.

The rear endof the bar D is grooved at d, (as in the end of bar D, see Fig. 6,) to adapt it to engage and be acted upon by the cam c, and is upheld by a yielding-rod andspring at (1, connecting it-with a supportingstandard or arm, d*, on the rear end of bar A in such manner as to be above the path of thecam 0, except when depressed by the attendant by means of a lever, E, the foot 6 of which overhangs also the bar D, for simultaneously de-' plunger D for moving the parts a and a inv the operation of upsetting the iron.

The partsa and a? of the die are stationary in the process of upsetting the iron, and may abut against the rear face of the forwardiwall of the recess in the table for that purpose; but,

. in the drawings they are shown. supported ger D. after they have been operatedtoclampagainst the upsetting thrust of the plunger and, movable dies. by means of bracketsf and, f, secured, one to the longitudinal sidewall, A ,and the other to the laterally-moving bar A, said brackets overhanging the partsofthe die,,as shown in; Fig. 4., andprovidedonlthetr forward edges with hooksf, which engage pins. a on the parts a antler, of the-die, preventing longitudinal movement of saidparts, and on their rear edges with tongues or spurs. ffiwhich engage pins (1 on, the partsa and a of the die, permitting longitudinal. movement of said lastnamed parts, but preventing; lateralmovement except as the parts a. and a move with the bar A.

'Forwithdrawing the bar A and the plunandupset the metal, as described, I connect.

them, through rods. D and D* to slotted arms G and G, pivoted on a short shaft or shafts at G and provided with forwardly-projecting toesg and. g, which overhang the cams a and" c, and are acted, upon thereby, said camsv serving to rock the arms. G and. G back on.

their pivot, and so to retract the bar AP and. the plunger for releasing the barof iron after it has been operated upon, in a: manner that will be readily understood. By adjusting pivots connecting the ends of rods D and D with the arms-G and G up or downin the slotsg therein the backward movement or thrust of the rod or bar A and. of the plunger D can be varied, as desired, for varyingv the throw of themovable parts of the dies and. the consequent amount of stock that can be upset. thereby.

The plunger Dhas rods 01' and d secured to and moving with it, which project rearwardly and move in suitable guiding and steadying brackets on the table, and have tappets 11 and d secnredto them, which, as the plunger D is withdrawn, comein contact with the pins or on the movable parts of the die, and serving to retract the latter, and thereby to release the iron operated upon. The bar A and movable clamping portions of the die may be moved laterally for releasing the iron by means of a spring, as described in my other application referred to.

-The bar A has on its upper face a pin, h, which passes through a slot, h, in a bar, H, resting and sliding on the bar A, the slot and pin referred to limiting the relative longitudinal movement of bars A and H.

The ends of bar H have pivoted to them one arm each of two. bell-crank levers, I and 1 which. are pivoted at their angles to the side A of the frame, the other arms of said levers,

being connected by links I and I with the.

bar A, said links, acting like the linksof, a,

parallel-rule, steadying the niovementsofi the barA and assisting to. move it upitoandlto. withdraw it from its work of clamping the irons.

K isarod. secured andsupported at its rearend in a standard or bracket, K, secured to Qany, suitable fixed portion of the frame, the

rod K projecting forwardly from itssupport and overhanging the slot in the frame and the.

longitudinal opening betweenthe parts of the. diet. Uponthis rod. are secured adj ustably two or morependent hooks, 7c and 70', one infront and a second in rear of the die, and=within which. the iron to be operated upon islaid,

said hooks being of suitable length. andarrangement to hold. the iron in proper relation to,the parts of the die.

The dies may be similar in construction. to those-described in my other application, referred.to,that shown in Fig. 8 being composed" of. four parts, a, a, a and aiadapted to bothclamp and, upset the metal between them, as

explained, and toform an angle andknobor. collar thereon, while the two parts, showain.

Fig. 8, forming one half of the die, are shown provided with sockets hexagonal or polygonal.- in form, and in both ends of said, half of the. i .die, adapting it to be turned end for end when scribed. may be constructed, and. arranged as,

in my other application referredto, or in. any suitable manner.

- Having now described my. invention, Iclaim= asnew-= 1. In amachine for upsetting carriage-top and other similar irons, the cam projectionon.

the shaft for actuating the crosshead. on plunger, in combination with the slotted vibrating arm for retracting the plunger, and
